Lawmakers and the tech sector are pushing U.S. Trade Representative Ron Kirk to back their campaign against an Indian government procurement policy known as “buy India.”

Despite previous U.S. pushback, India recently took another step to implement the new policy requiring a certain amount of domestic content in electronic goods procured by its government — and possibly all Indian companies as well. That’s alarmed tech companies and their Capitol Hill allies.

“We feel the Indian government has basically ignored our request to revise this policy even though it’s been raised at very high levels,” said John Neuffer, vice president of global policy at the Information Technology Industry Council.

Because the Indian government first unveiled the policy, formally known as preferential market access, last February, Neuffer thought progress had been made in talks with Indian government officials. However, Neuffer told POLITICO he was disheartened to see the Indian government’s latest guidelines on the PMA, which only heightened tech industry concerns.

The new guidelines, issued last month, suggest that the Indian domestic purchase requirement may extend beyond government procurement and into the private sector. Depending on how the Indian government carries that out, it is a possible violation of World Trade Organization obligations, U.S. officials say.

Lawmakers are helping to ramp up the pressure against the buy-India mandate.

Reps. Doris Matsui (D-Calif.) and Mike McCaul (R-Texas), leaders of the Congressional High Tech Caucus, sent a letter to Ambassador Kirk on Tuesday calling on him to pressure the Indian government to back off its plans.

“We are writing to request that the U.S. Trade Representative’s Office take urgent action on the recent Preferential Market Access (PMA) Policy issued by the Government of India,” the lawmakers wrote in draft language obtained by POLITICO. “The potential detrimental impact of this policy on U.S. high-tech exports to India warrant USTR’s consideration of all available tools to ensure U.S. technology companies are able to compete fairly in this critical market.”

Last June, 21 members of the House, including Matsui and McCaul, wrote to Indian Ambassador Nirupama Rao to highlight their concerns with the policy and call on the Indian government to reconsider it.

The Indian Embassy did not respond to multiple requests for comment on Monday.

“The Office of the U.S. Trade Representative has been actively engaging the government of India on this priority issue and will continue to intensify our efforts to ensure nondiscriminatory access to the Indian market for U.S. goods and services,” a USTR official said Tuesday. “And we look forward to continuing to work with Congress as we do so.”

If India doesn’t change course, Neuffer worries that other countries will follow suit — and that, Neuffer said, could be disastrous for tech.

“The entire business model for the tech sector is threatened by local content requirements,” Neuffer said.
